Adding basic classes/types ​

At any level of the model, you can add types/classes if you need to and if you aren't lazy. When you realize that a physical object, class, and tuple are not a sufficiently expressive language to annotate your entire domain, or at least the annotation of objects is not very convenient, you may want to create shortcuts to talk about your familiar subjects.

If you can determine where your new types/classes belong in the top-level ontology, you don't have to think every time about how to place and format them.

For most of us, our area of interest is related not only to the physical world but also to roles and descriptions. We will explain how a couple of convenient types emerged and how to use them.
